Aspheric Lenses are used to eliminate spherical aberration in a
range of applications, including bar code scanners, laser diode
collimation, or OEM or R&D integration. Aspheric lenses utilize
a single element design which helps minimize the number of lenses
found in multi-lens optical assemblies. Said another way, unlike
conventional lenses with a spherical front surface, aspheric lenses
have a more complex front surface that gradually changes in
curvature from the center of the lens out of the edge of the lens.
This reduction in total element count not only helps decrease
system size or weight, but also simplifies the assembly process.
Integrating aspheres into an application such as focusing the
output of a laser diode may not only decrease total cost, but may
also outperform assemblies designed with traditional spherical
optical lenses.
An aspheric lens or asphere is a lens whose surface profiles are
not portions of a sphere or cylinder. In photography, a lens
assembly that includes an aspheric element is often called an
aspherical lens.
Aspheric elements are used in the design of multi-element
wide-angle and fast normal lenses to reduce aberrations.
While in principle aspheric surfaces can take a wide variety of
forms, aspheric lenses are often designed with surfaces of the form
Aspheric lenses primarily in high efficiency illumination systems,
aspheric condensers offer superior aberration correction. Our
aspheric lenses are ground and polished on the plano side and
precision molded on the aspheric side.
